Asus ROG Strix Z270G Gaming Review

A quick look at the Asus ROG Strix Z270G Gaming reveals that the Micro ATX motherboard is loaded with features that are directly comparable in quality and number to those of any ATX motherboard around its price range. As it is 59 mm shorter than an ATX motherboard, the Asus ROG Strix Z270G Gaming has three fewer expansion slots. The configuration that Asus went with is two full-length PCIe ×16 slots (×8/×8 in SLI/Crossfire) and two short PCIe ×1 slots. There are two PCIe ×4 M.2 slots and six SATA connectors, which ought to be enough for the storage requirements of any gaming or home entertainment system. There are no native U.2 connectors, but U.2 drives can be connected to the M.2 slots by using appropriate adapters. Asus does not add any SATA Express connectors on most of their gaming range motherboards and the ROG Strix Z270G Gaming is, expectedly, no exception to that rule.

The controllers of the ROG Strix Z270G Gaming motherboard are interesting, yet nothing out of the ordinary for a motherboard of this class. For audio, Asus is particularly proud about their “Supreme FX” audio system that implements the Realtek ALC S1220A (aka ALC1220A) audio CODEC and is placing a lot of their marketing efforts on it. The single wired Gigabit LAN chipset is the very popular Intel I219-V, with Asus expressively advertising the implementation of their surge protection feature called “LANGuard”. Asus has also added a WiFi/Bluetooth module from Qualcomm (Atheros QCNFA364A). Finally, there are two USB 3.1 controllers from ASMedia, one for the rear USB 3.1 Gen 2 ports (one Type-A and one Type-C) and one for the internal USB 3.1 Gen 2 header. At this point, we should also mention that the ROG Strix Z270G Gaming is the first Z270 motherboard that we have tested that has an internal USB 3.1 Gen 2 header.

From our testing, the Asus ROG Strix Z270G Gaming performs well under its default settings, with the spotlight being its extraordinary audio performance. In terms of raw speed and/or stability, it does not differentiate from any other typical Z270 motherboard, except when compared to models that do not have multi-core turbo enabled by default or are practicing overclocking under their default setup. We also acquired very good overclocking results that will certainly please more advanced users who are planning on building a very powerful cost-effective gaming system.

In comparison to the older Z170 boards, the Z270 boards on the base specifications are hardly any different. The Z270 ones have four extra PCIe lanes configurable on the chipset, potentially new audio and new networking controllers, and Intel Optane Technology Support. Although four extra PCIe lanes do sound like a huge difference, it is an important upgrade for the implementation of native M.2 slots (on Z170-based motherboards, this usually meant disabling some other device/port on the motherboard). Also, note that Intel Optane drives should still function on other chipsets as drives; the Z270 only allows them to enable their “smart caching” technology.
